Casting Benedict Cumberbatch as Khan Singh made about as much sense as casting Jessica Alba as a blue-eyed blonde in the Fantastic Four movies - couldn't Cumberbatch simply have played another genetically-engineered superman from Khan's crew? If they wanted to give a nod to Space Seed/Wrath of Khan, then when they were putting all the cryo-pods into storage, why not show one of them being wheeled past, giving a quick glimpse of Ricardo Montalban's face superimposed in the viewing window?
